JOSHUA R. RITCHIE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALFTO WILLIAM ABBOTT, OF SAME PLACE.

REVERSIBLE SEAT.

SPECIFICATION forming part of Letters Patent No. 318,296, dated May 19,1885.

Application filed February 20, 1885.

To all whom it may concern Be it known that I, JOSHUA R. RIToHIE, acitizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Reversible Seats, which improvement is fully set forth inthe following specification and accompanying drawings, in which Figure 1represents a top or plan View of a chair embodying my invention. Fig. 2represents a vertical section in line as a, Fig. 1. Fig. 3 represents avertical section in line 00 m, Fig. 1, on an enlarged scale, the backand arms of the chair being removed.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a chair, stool, 800., having a reversible seat,the construction and operation thereof being hereinafter fully setforth.

Referring to the drawings, A represents the seat of a chair or stool,and B represents the support thereof. The seat has two faces, C C, oneof which is upholstered and the other made of perforated wood, althoughany other suitable material may be used, and theseat is removable fromthe support, whereby, by reversing it, either of its faces may be placedabove, and thus different kinds of seats may be presented; or if bothfaces are of the same material and one face is worn, the other face maybe brought into service.

The side of the seat-frame D is doubly rabbeted, and the inner side ofthe seat-support has a shoulder, E, on which the central rim, F, formedby the rabbets, is sustained, said shoulder occupying the lower rabbet.In the upper rabbet is placed an annulus, G, which is flush with theseat-support and coincides with the shoulder E.

H represents bolts or screws which are employed for connecting theannulus and seat (No model.)

with the seat-support, said bolts passing through the annulus Grand therim F and entirely through the shoulderE, so as to receivetightening-nuts on their lower ends, or may pass through the shoulderand rim into part of the annulus; or they may pass through the annulusand rim and screw into the shoulder. When the annulus is made of castmetal, screw pins or bolts may be formed therewith, the ends thereofhaving nuts which tighten against the under side of the shoulder.

It will be seen that when the bolts or screws are released the annulusmay be withdrawn from the rabbet it occupies. The seat may then beremoved, reversed, and reapplied. The annulus is reapplied, and thebolts and screws are tightened, whereby the seat is firmly connected inposition, it being seen that the annulus provides a metal fillingbetween theseat support and seat frame, and as it is clamped to saidsupport and frame it serves as a re'enforce to said parts, so that astrong and durable seat is provided.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A support having a shoulder, and a reversible frame having a centralrim formed by double rabbets, in combination with an annulus which iscoincident with said shoulder, whereby the rabbets are occupied by saidshoulder and annulus in either position of the frame, substantially asand for the purpose set forth.

2. The doubly-rabbeted frame having a central rim, the support with ashoulder, an annulus, and fastening bolts or screws connecting saidannulus, frame, and support, substantially as and for the purpose setforth.
